I heard that the dismissal of ETH cost Leverkusen 5 million. On the one hand, it's a lot for 2 games (excluding the cup game), but on the other hand, with modern prices in football, it's nothing. It can be assumed that Leverkusen saved a lot by losing these 5 million. This is literally a stop loss 
Hehehe i'd rather call how Lucky Ten Hag is as Leverkusen paid him millions just to be spectators only for two weeks. I also don't feel bad for him as he made more money than what we made entire life. I will be waiting for a motivation book by him about how he made millions just in less than a month by doin nothin. It's something that is worthy to wait.
